My Plex server is no longer showing up when I log in

NAS Model: Synology DS20+
DSM Version: DSM 7.2.2-72806 Update 3
Following the steps in this article did not restore access.

I am seeing my Plex Server (NAS-1) listed in the left menu when I go to Activity > Dashboard (see attached) but I’m not able to get any of the content to show up.
